Swing & Cyclone Bros.
Go to the hammerhead's second house and break the rocks on the right. Then go up them and talk to the block guy. He'll tell you to hit a block. Always hit the middle one and you will get a scroll. Mario or Luigi will read it and say they have mastered jump or hammer. Then get in to a battle and go to bros. attack. it will say: Swing or Cyclone bros. Use it in lvl. 1 and practice untill it is easy. This hint is really there!!!

Beat Trunkle easily
Trunkle might be hard to beat but you can beat him a easier
way instead of doing damage to the lower part of him attack
the tree on his head with all of your strongest bros attacks. Trunkle cannot revive that part by sucking in the enemies and shrooms and you wont have to worry about that attack where he splits in four. Just remember to attack the tree.

Unmovable Mario
Turn Luigi into a surfboard and surf to the coast on the east side of Beanbean Castle Town. Surf in and land on the shore. While Mario is dismounting the surfboard, hit a Bob-omb to start a battle. When the battle is over, Mario will be frozen in the air, but the pause screen will still be accessible.

Infinite Coins
First hit Mario with the hammer to make him Mini Mario.
Change Luigi's command to High Jump. When Luigi is in the air, make Mario jump. Jump repeatedly to keep Luigi in the air. Every time Luigi is hit you gain 1 coin, but Luigi loses 1 health. Luigi's health cannot go below 1.

Music from one place to another
Before entering a pipe, enter it with Mini-Mario. During the Pipe-Selection Screen, the music in the previous area you were just in will stay the same. When you warp to your destination, the music in the pipe will now be the BGM until you leave the area/go into pipe while not Mini-Mario, etc.

Permanent Red Pepper Result!
Red Peppers increase your power for a few turns. During the effect, let the effected brother get knocked out. Then, use a 1-UP Mushroom to revive them. The effect will continue for the whole battle and not wear off! This is especially useful against hard bosses.

Easy stats
In beanbean catsle town go to the place where you make juice out of beans.and make anything then the proffeser will come out and give you a reward then make the same juice again and press select then you will see the juice were the items are. use it then it will increse a stat ( note- you can do this mutiple times)

Game references in the Yoshi theater
In the lobby of the Yoshi theater, there are four posters on the wall referring to Nintendo video games:
1. Kirby Story--referring to the Kirby series
2. Wario poster--referring to the Japanese box art design for "WarioWare, Inc.: Mega Microgames"
3. M&L--referring, of course, to this game (more specifically to the game's originally intended title, "Mario & Luigi")
4. Legend of Stafy--referring to a Japan-only game series of the same name

See Princess Peach's Castle
Go to the summet on HooHoo Mountain, walk to the top right of the summet until you get to the edge. There should be a slant in the summet shape (like an octogon) and two stone sharp-like rocks, walk up to the top one and look underneath the B button icon, you should see Princess Peach's Castle from Super Mario 64.

Gold Beanie
Sometimes you can see a Gold Beanie on a rare occasion. If you defeat it and it does not flee, you will get a Spike Badge. You can see them by killing some of those spiny creatures in Chucklehook Woods or underwater.

Luigi surfboard
When you get the Ultra Hammer, go to the beach where the surfer is located and talk to him. He will say that you need something to pound into the slot. Switch Mario to the back and use your hammer over the slot to make Luigi fall in and pop out as a surfboard.

Easy dodge
Sometimes it is hard to dodge a monster's attack because you pressed the wrong button. If this keeps happening, try pressing (A) + (B).

Cheaper photos
A photo cost 100 Coins from the photographer near Queen Bean's castle. However, you can lower the price to 50 Coins if you choose "No".

Battle options
During a battle, do not choose the option to run. This only takes away some of your coins and starts the battle from the beginning.

Finding items
Learn how to use the hammer technique. Then, hit Mario with a hammer and make him small. When Mario is small, an exclamation mark will appear over his head when he is over a buried item (and increase if he is directly over it). Without walking, switch places so that Luigi is in front then Mario hit him in the head with the hammer. Pop out and you will have your item.

You can find many items in flower circles or Xs in the ground.

Weird passport pictures
When taking your passport pictures on the Koopa Kruiser, the baddie will say "Do not move". Move once, then he will say something to you. Then just when he is about to take the picture, move the D-Pad. When done, look at the passports.

Change music
To change the music in any area to multiple songs, do the following things. Get the hammer later in the game and get to a pipe used for changing worlds. Turn Mario small and go into the pipe. The music will be the same when you change worlds.

Donkey Kong reference
At the skeleton ship, when you play the barrel mini-game, the skeleton is actually in the shape of Donkey Kong.

Legend Of Zelda reference
One of the items that Professor E. Gadd gives you is an item called "Great Force", which actually looks like a Triforce piece.

Luigi's Mansion reference
Go to the cafe in Beanbean Castle Village. Then, talk to the man at the stand. He will let you select a blend. Choose HooHoo Blend. Soon after, a ghost will appear, then Professor E. Gadd will show up. Note: You will need to use beans.
